Improvements in lraotion-Machines, of w iioh the following is a fol. clear, and er;- act description.

This invention relates to an improved tractor to serve as the (lr 'e or propulsion means for appliances ceptihle oi the performance oi certain kinds of work.

The invention is described in conjunction with the accompanying drawings and is set forth in the claims.

In, the diairingsz-Figurc l is a side elevation of the tractor shown as serving for the draft of a plow. Fig. '2 is eplan View of Fig. l. is a sectional elevation as seen on a' plane of section centrally and vertically coincident with the axis of the tractor,that is on line 33, Fig. 1. Fig.

L represents a lever pivotally mounted at n on a bracket n provided on the carriage frame P is of bail or yoke form, and also as a transversely rear portion of the 5 such shaft the propulsion forwardly ofth e.

so that such lever may swing in a. vertical plane which is substantially coincident with the axis of the internal-track wheel 5 and the lower arm of this lever L which is of a fork or yoke shape, engages in the annular groove of the operating member In, (Fig. 8), or k (Fig. 9)-of the axially slidable clutch device. Through the tubular hubs of the internal track-wheel, a rod M is axially movable, the same having an appliance on anare connected by transverse and axially hori-' zontal pivots whereby the frame P may have a vertical swinging movement. This comprises the transverse rear member 9 which unites the side members Q. a One of the aforementioned sleeve members N is provided with a horizontal rearwardly extendin g bracket 8 on which a bell crank or angular lever t is pivotally mounted; and the forwardly extending armof this angular lever has as indicated aim! in Fig. 2, Ta stud and slot engagement with a portion of the aforementioned rod' M which projects at one side outwardly beyond the hub of the track wheel A. To the rearwardly located and disposed member of the anguhr lever t a thrust rod u is pivotally connected, the same ranging alongside one of the side members q of the frame P, and has a supporting and guiding engagement through an apertured lug 9 provided at a frame.

Assuming that the carriage supported englue is started running,by the means which it is understood'to be provided with,

for its starting and stopping-and the thrust rod u is moved in the proper direction, the latter will, through the angular ever t, cause an axial movement of the rod M, and a swinging movement of the lever L, thereby plating the sprocket wheel J in .clutch connection with the engine shaft and consequently causing from the rotations of of the track rollers T, which are engine su porting'carria'ge. Such carriage having a degree of movement forwardly and upwardly the wheel A, will produce a rolling movement of such wheel along the ground for whatever useful made to serve.

.As represented in Figs. 1 and 2, the side members of the frame P joined by the transverse intermediate member g to which the tongue of a plow'R is connected. The handles of the plow through depending eye, members at (1 so that when the apparatus is utilized as a plowing machine, the person grasping the handles of the plow and controlling the action ofthe latter may, at the same time, effect theguidance of the internal track wheel in its proper course: This being practicable as any transverse: force imparted to the plow handle, will, by reason of the engagement of the latter withthe frame P, correspondingly aflect such frame; and such frame bemg jointed to the sleeve member provided at the hulf of the track. wheel is directly effective for the guidance of the latter.

While the internal-track wheel is of such substantial width that it will be liable to fall over sidewise, there are occasions when means for the prevention of sidewise tipping-are necessary, such, for instance as when employing the tractor on a side hill; and with reference to Figs. 1, 2 and 3, it

will be perceived that the aforementionedsleeve members are constructed with socketed lugs '12 o offset from theaxial line of the sleeves in which depending members to are engaged and confined, which members are provided at their lower portions with 'r'evoluble in planes parallel with the plane of revolution of the track-wheel and have rolling bearingon the ground. When it is not necessaryor desirable to use these steadying wheels T T, the supporting members moved upwardly through the socket lug, or they may be removed from their fixed engagements therein.

As an example of one other,of the many utilizations which may be made of this traetor, I have represented it in Fig. 4 as a motive power for the drawing of a carriage W. Here the shafts w of the carriage are connected with bers N N-which are non-rotativelymounted on the hubs of the tractor wheel; and here for the guidance of the track wheel, a yoke frame P has the side members thereof connected to the opposite extremities of the aforementioned Qrod M which is mounted for endwise 'playgaxially through the track wheel. The side members of this bailshaped frame or yoke P 'is pivotallypon.
